Adafruit LTC4311 I2C Extender / Active Terminator - STEMMA QT / Qwiic Pi 400 Kit open-drain outputs for LED control

open-drain outputs for LED control

so this cable must be connected to a client device to pull the CC line low and activate power supply

allowing you to control 5V LCDs even when using 3V power and logic

so anything you can do with RFID you can do with NFC

Adafruit LTC4311 I2C Extender / Active Terminator - STEMMA QT / Qwiic Pi 400 Kit open-drain outputs for LED controlI2C is designed for short distance communication on a PCB, but extending it over long cables introduces capacitance and resistance that can slow down signals. The Adafruit LTC4311 active terminator solves this by boosting the I2C bus rise times, enabling much faster data rates over long cables without complex hardware changes. The LTC4311 is easy to usesimply connect it to your I2C bus (usually at the start of the chain). It automatically detects
